ART. OF ROLLING.

Application filed October 3,

To all whom it may concern Be it known that I, NORBERT METz, metallurgist, a subject of the Great Duchess of Inlxemburg, residing in Diidelingen, Great Duchy of Luxemburg, have invented new and useful Improvements in the Art of Rolling, of which the following is a specification.

This invention relates to a universal rolling mill which enables me to complete the rolling of I-beams by means of one single set of rolls arranged in one single frame and consisting of two horizontal and two vertical rolls. WVith the said two horizontal rolls four ring-shaped auxiliary rolls or collars are connected which when laterally clis placed project into circular grooves or recesses in the front faces of the vertical rolls. In this manner I may attain that (1) the web faces, the interior faces and the edges of the flanges can be operated upon when all the four auxiliary rolls join the horizontal rolls; (2) the web faces and the interior and exterior faces of the flanges can be operated upon when all the four auxiliary rolls are separated from the horizontal rolls.

The invention is illustrated in the accompanying drawings, of which Figure 1 is a front view of the rolling mill, Fig. 2 is a side view of the same,

Figs. 3, 4t and 5 show the horizontal, vertical and auxiliary rolls in different positions,

Figs. 6 and 7 show, on an enlarged scale, the rolls in two different positions with a modified form of the auxiliary rolls or collars.

In all the figures a represents the horizontal rolls, 5 the vertical rolls and c the auxiliary rolls or collars. The driving mecbanisms for operating-the rolls are marked d, c and 7. In the example illustrated by the drawings electromotors provided with worm and wheel gearing are employed. The upper roll is balanced in the known manner.

The rolling process shall now be explained referring to Figs. 3 to 7.

After the suitably pre-profiled bar to be rolled has at first been treated, be it simul taneously or subsequently, only with the horizontal rolls aand vertical rolls 5 the collars c resting on the rolls are as soon Specification of-Letters Patent.

as the flange has attained the suflicient Width, pushed forward so that the edges of the flanges can be operated upon, 2. c. the two upper and the two lower collars are alternately advanced, the collars not in operation projecting into the corresponding recesses of the vertical rolls 1), as shown in Figs. 3 and 4.

Of course it is also possible to operate upon the flange edges at the same time with all the four collars if desired, as shown in Fig. 1.

In Fig. 5 I have shown in what manner in the finish the collars are removed and the flanges are smoothed and straightened by means of the vertical rolls.

To avoid the formation of sharp edges on the flanges at the point where the collars touch the horizontal rolls, I may modify the collars in such a manner that they do not only cover the flange edge but also partially the inner face of the flange.

Fig. 6 shows one of the collars of this modified form in cross section operating together with the horizontal rolls ea. As is seen, a sort of flange g of the collars c overlaps the conical parts of the horizontal rolls, whereby the flanges of the beam are compressed and bent outwardly.

In Fig. 7 I have shown the manner in which the beam flanges are again set straight in a subsequent operation by means of the vertical rolls Z).

The same form of collars is also applicable when the beams, as shown in Figs. 3 and 4, are simultaneously operated upon by the horizontal rolls, the vertical rolls and at one side by the collars. In this case it is necessary to make the flanges g of the collars 0 end with a sharp edge in order to avoid the formation of undesired edges on the inside of the beam flanges.

Having now fully described and ascertained the nature of my invention, what I claim as new, and desire to secure by Letters Patent is:

1. In a rolling mill for rolling I-beams, the combination in one single frame of two horizontal rolls rotatable in vertical direction and two vertical rolls rotatable in horizontal direction with rolling collars slidable on the shafts of the horizontal rolls and projecting into circular recesses in the faces of the vertical rolls.

2. In a rolling mill for rolling -I-beams, provided with flanges adapted to partially the combination in one single frame of two overlap the horizontal rolls. 10 horizontal rolls rotatable in Vertical direc- In testimony whereof I afliX my signature tion and two vertical rolls rotatable in horiin presence of two witnesses.

5 zontal direction with rolling collars slidable NORBERT METZ.
